It is a mystery

 I swear I've had normal days. But not today. I stayed up a bit late last night reading because my stomach was upset. Then I woke up this morning, felt normal until about 9 and got dizzy all of a sudden. I was able to get my field work done and just got back home. Standing was fine, sitting was fine, doing anything else is not great. Still dizzy 3 hours later. I'm taking a nap and then I need to get a work thing mailed and look at bugs. Seriously body wtf
ETA: feeling much better after nap, who even knows
